Continuous Slot Pipe Based Wedge Wire Wrapped Screens

Product Description

Product description of johnson continuous slot pipe base screens wedge wire wrap well


The continuous slot johnson wire well screens pipe made by winding cold-rolled wire, approximately triangular in cross section, around a circular array of the longitudinal rods. The wire is attached to the rods by welding, producing rigid one-piece units having high strength characteristics at minimum weights. The advantages of John type screens are as follows:

1. Better filter function. The V-shape section plane of water well screens(Johnson screens) creates the continuous slot, which can avoid blockage and make sure of the unimpeded water.

2. Prolong life of well. The consecutive slot of water well screens(Johnson screens) have wider open area, and it can reduce the speed of the water entering to avoid the sand entering the screen under the great pressure, so it can control sand better, which can increase water yield and prolong service time of the well.

3. Long service life. Wire and support rods are all-welded, which makes water well screens(Johnson screens) more robust and longer life.

4. High pressure-resistant. The longitudinal support rods and the continuous slot make the water well screens(Johnson screens) have more excellent pressure-resistant performance.

5. Customized. Specifications and end connections of water well screens(Johnson type screens) can be fabricated according to customers' requirements.
